LIQUID-FUEL BURNER.

Specification of:Letters Patent. Patented Apr.22,41913.1

Application fi1ec 1May.28,11912. Serial nonzooaaa To all whom it may concern Beit knowna that I, GEORGE:R. Barn, a citizen of the United States, residing at Lees Summits in the county of Jackson a and Stateof Missouri, have invented a new and useful Liquid-Fuel Burner, of whichnthe followingis a specification. a a

This vinventionihas reference to improve-1 ments in liquidilfuel burners, andQits object to provide. a means for the efficient combustionof liquid fuelm a 1 In accordance with thepresent invention thereiis provided a. water receptacle with? means for maintaining a substantially con? stant level of water therein, and :thisrecep tacle has introduced therein a nozzle carrier directed toward the water in the receptacle with the feedpipeto the nozzleipassing throughithe water within the receptacle and receiving liquid fuel from a suitable source usually contained in a tank provided with means for causing air pressure therein. The jet of fuelis directed toward the water so that: the burning fuel strikes the water and. vaporizes the latter and the mixed pifuell and vaporized water cause a smokeless flame. to issue from theburner, the. vaporized wa: ter being heated to such a degree as to be decomposed and; therefore on reunion of its components; produces an intensely hot: flame. y

The invention; will be best understood from a iconsideration of jthe following de-= tailed description taken inconnection Vithi the accompanying drawings forminga part of this speoifioation, with the further under standing that while the drawings show forms of the burner. whichin practice prove etficient,: the invention may assume other practical forms embracing the same salient: features as the forms illustrated, wherefore the invention is notlimited to any exact cons formity with the showing of the drawingsa In the drawings :-.Fi,gure i l is a a vertical section through-la burner constructed in accordance with the present invention with some parts shown in elevation and a stove or closure for the burner indicated 1 i111 dotted: lines. Fig.12Iis a longitudinal sec-: tion on alarger scalevthan Fig. 1 of a jet device employed lwhen gasoleneolmthe like is the fuel. Fig.3 is an end view of the device of Fig. 12.5 Fig. 4 isa :view similar to Fig; Qbut illustrating the form of noz -w zle employed when kerosene or :like fuel is. used. Fig. 5is an end view of the strluo-- tureof Fig.4. p v Beferringito the drawings, there is shown in Fig.1 a casing l which may be taken as 1 indicativeof any stove structure or inolosure for. the burner, and while noattempt 1 is made to show any particular structure of stove, 1t :wlll be understood that thestuuc-v ture is such as tolpermit the use of a burner of the presentinvention. In the particular showing of Fig; l itwo. cylindrical. members 2-2areaindicated, but it will be under stoodjthat this constitutes a double burner, and that so far asuthe structure is -co'ncerned .a single cylindrical lmember 2:1nay be used,: or more than: two: may be ;used. Each cylindrical member 211115 a closed bot-1 tom 3 and is open atthe top as idicated IELt 1 l, it being understood that in practice the cylindrical members are placed. upright: These members are located within the stove 1 and are suitably separated, andConsidering that there are two members 2, they are connected together by a pipe 5-at a short distance above the bottom: 3, this being a free connection so that if water, indicated at 6, be introduced into one member 21it will iflow into the other member 2 until at: the same level. Extendingifromone of the members 2 is a pipe 7 which may be at the same level as the pipe 5, although this is not mandatory. The pipe .7 extends to the exe terior of the stove body 1 and leuters a tankvS :below the upper end thereofysvhich upperaend maybe open. The tank 8 re-- ceives a belly?) having a filling opening L01 mally closed by arplug 10; and near the bot tom the hell 9 isprovicled with an orifice 11. If it be assumed that the bell 9 is filled with lwater, such waterwill find its way out througligthe orifice 11 into the tank 8 until.

ably placing the tankB, the level of water therewithin will? determine the level of wa-i ter within the cylindrical members 2.

Entering each cylindrical. member 2 through the bottom31is a pipe ;12whicl1 maybe carried up through the water6 to near the top of the member 2, and then die rected downwardly and at its end is pro- 'vided with an externally screw-threaded portion 13 adapted to receive a nipple 14: or 15 as the case may be. Each pipe 12 is provided with a controlling, valve 16, and the valves are inturn connected to a common supply pipe 17 coming from a closed tank 18 containing the supply of fuel. This tank may be provided with a pump 19forestablishing, air pressure-therein, and a gage 20 for indicating the pressure, while fuel may be placed in the tankthrough an opening normally closed by a plug 21. The nipple 14 is shown as provided with a single escape orifice 22, while the nipple 15, which is latnumerous escape orifices 23.

It W111 be understood, of course, that where but a single burner made 'up of the cylindrical memberQJand the parts contained therein, is employed, the pipe 17 will connect directly to the valve 16' for said burner and where more than two burners material is the fuel, it beingfound advisable to cover a greater area with the fuel in the latter case than where gasolene is employed.

If it be assumed that a suitable pressure has been established within the tank or reservoir. 18 andthat a suitable amount of water has been placed in the bell or supply member 9 and has filled the cylinders 2 up to the desired level, above which these cylinders may have orifices 24, then on opening the valve or valves 16 fuel lwillfflowto the jet nipple and may be there lighted and the flame so caused is a directed against the water, the combustionbeingjefi'ected by air entering through the orifice 24. The flame will quickly convert the water into steam and superheat the steam, so that it tends to steam is separated into its component parts wh ch will reunite .for the productionjof an intensely hot flame, wherein all particles of carbon are thoroughly burned and a smoke- 55. less flame results As the water within the members or burners 2 .is evaporated the supply within the tank S is drawn open and ultimately the level within said tank sinks sufliciently for the entrance of air through theorifice 1 1 and water is'thereby permitted erally expanded, as shown, is provided with are employed acorresponding;number of augment the supply of oxygen and the stant and V the action of the burners continues indefinitely to be controlled at will by e a manipulation of the valves 16 andflthe casing There are no vaporizing pipes or V sprayingjets to become clogged up and thermore the fuel supply pipe is carried" through the body of water so that the fuel supply at notime becomes unduly heated before reaching the jet end .of the burner pipe, and consequently there is no deposition of carbon or superheating' of the-fuel before it issues from the ct, What is claimed is IQA burner for liquid-fuel comprising a casing open at the upper end an closed at the lowerend, means for supplying water to the casing and maintaining ,1t thereln at a Y predetermined level-and 'a supply pipe for fuel'enteringthe chamber upwardly from therbottom thereof and terminating above the predetermined level for the water in a jet member directed toward saidwater level,

the upper end of the water container being I.

open. v
